Assignment InstructionsDevelop a 4-5 page essay that fully responds to the following prompt:Prompt: The Department of Homeland Security's 2014 Quadrennial Homeland Security Review identifies six strategic challenges (found on page 28 of this document) that it believes will drive risks facing the nation over the next several years. Explain the process used by local communities (counties or cities) in determining which of these threats pose the greatest risks to their respective communities, and how these communities prioritize their resources in attempting to prevent or mitigate these threats. In addition, what steps and actions might be taken by these communities to prepare for such events in a proactive and effective manner?(Note: The six strategic challenges are: The terrorist threat, cyber threats, biological concerns, nuclear terrorism, transnational criminal organizations and natural hazards. Do not confuse these with the Department of Homeland Security’s five missions)Technical Requirements:Length: 4-5 pages total, double spaced, 1" margins, 12 pitch type in Times New Roman font.

Week Three - Application AssignmentAnswer the following questions in a Word document and upload the document to the appropriate drop box.1) A museum borrows $2,000,000 at simple annual interest to purchase new exhibits. Let x represent the amount borrowed at 7%, y represent the amount borrowed at 8.5%, and z represent the amount borrowed at 9.5%. Set up a system of linear equations to determine how much is borrowed at each rate given that the total annual interest is $169,750 and the amount borrowed at 8.5% is four times the amount borrowed at 9.5%. You do not have to solve the system.2) At a local store, the numbers of gallons of skim milk, 2% milk, and whole milk sold over the weekend are represented by a matrix A. Skim 2% Whole Friday 40 64 52 Saturday 60 82 76 Sunday 76 96 84The selling prices per gallon and the profits per gallon for the three types of milk are represented by B. Selling price Profit Skim $3.45 $1.20 2% $3.65 $1.30 Whole $3.85 $1.45 a) Compute AB and interpret the result. b) Find the store's total profit from milk sales for the weekend3) A florist is creating 10 centerpieces. Roses cost $2.50 each, lilies cost $4 each, and irises cost $2 each. A customer plans on spending $300 on 10 centerpieces with each centerpiece containing 12 flowers, with twice as many roses as the number of irises and lilies combined. a) Write a system of linear equations that represents the situation. Then write a matrix equation that corresponds to your system. b) Find the number of flowers of each type that the florist can use to create the 10 centerpieces.4) One hundred liters of a 50% solution of a chemical mixture is obtained by mixing a 60% solution with a 20% solution. Using a system of linear equations determine how many liters of each solution are required to obtain the 50% mixture. Solve the system using matrices.
